CARPET-CUTTER.

SPECIFICATION formingpart of Letters Patent No. 245,049, dated August 2,1881.

` 4 Application filed April 25, 1881. (No model.)

To all whom it may concern 4 Be it known that I, DIXON BEAN, a citizen lof the United States, residing in the city of a: :v in Fig. 1. Fig. 3 isa section on the line y y in Fig. l. Figs. 4, -5, and 6 are sideelevations of modiedforms of the blade. Fig. 7 is a section on the linez z in Fig. 5.

The same letters denote the same parts in all the figures.

My invention relates to implements for cutting carpets or oil-cloths.-These are frequently made in double breadths, and oil-cloth,

even when not made double, has often a considerable surplus of breadthwhich it isworth while to save. The separation of the breadths andremoval of the marginal surplus in thesev cases is now made by the useof shears or a knife-a `process both slow and inconvenient.

-The object of my invention is to make the process convenientand rapid;and it Consists4 in a cutter arranged to be propelled smoothly throughthe carpet by means of a long handle attached to it at a convenientangle.

It consists,further,in a pivotally-adjustable blade having a continuousedge, so that when one part of the edge becomes dull another part may bebrought into use by giving'the blade a slight rotary motion.

It consists, also,in the particular devices and combinations of deviceswhich will be fully described hereinafter, and definitely pointed out inthe claims.

In the drawings, A denotes a horizontal plate of metal or other suitablematerial, flat on its under side, and with an upper surface sloping toathin edge all around, so that the plate may slip readily under a carpetor oil-cloth. From the rear end ofl this plateiashank, B, extends upwarda-nd backward at a convenient angle for pushing the plate 4horizontallyforward by means of a long handle set in theupper en d of the shank, anangle of -about fortyfive degrees being preferable. The lowerpart, b, ofthis shank is thin, especially ou the front edge, so as to pass readilybetween the severed breadths of carpet. The upper part, b', expands intoa hollow cylinder, so as to be a socket for the handle.

A little above the plate A the part b of the shank is perforated, so asto allow a bolt, C, to pass through it. This bolt is threaded at oneend, and is enlarged at the other, so as to form a convenient handle, c,by which it may be screwed or unscrewed. A nut, D, shaped outwardly likethe enlarged part of the bolt, fits on the threaded end of the bolt, soas to rest squarely against the side of the shank.

The blade E is perforated in its center, e, so as to allow the bolt topass through it, theunthreaded part of the bolt being long enough topass through the sha'nk and afford a bearing outside of it for theblade. The perforation in the blade is large enough to allow it to turnfreely on the bolt, so that it may be adjusted in any desired positionin the saine vertical plane. A slot, a, in the horizontal plate allowsthe blade to pass through the plate. When the blade is setin theposition desired the nutD is tightened, and itis held firmly between theenlarged pant c of the bolt and the side of the shank. This claspin g ofthe blade against the shank may be aided by the interposition lof awasher, F.

The blade is edged on its entire periphery, so that when that part ofthe edge which is used in cutting becomes dull the nut D can be loosenedand another part of the edge be brought into service by a very slightturning of the blade, only a very small part of the edge being actuallyin contact with the carpet or oilLcloth in any one position of theblade.

`By this expedient it will be only at long in- IOO 2 Macao same sideofthe shank on which the blade is set permits the blade to turn througha coniplete circle, the thickness of the plate in that part beingsuficient to allow the blade to be 5 pivoted 10W enough to give ahorizontal eut in every position, while not allowing its lowest part totouch the floor.

By placing the bolt-hole higher on the shank the slot might he dispensedwith but the 1o contact of the edge with the carpet would, in

some positions of the blade and in every position of the circular blade,shown in Fig. 4, be unfavorable to an even and easy cut.

In operation the forward end of the plate A x5 is slipped under thecarpet to be cut, and the cutter is then pushed along by the handle setin the upper part, b, of the shank. The nut D and the enlarged part c ofthe bolt serve as guides to keep down that part ot' the carpet 2o whichis being out.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In a carpet-cutter, the slotted horizontal plate A, in combinationWith a shank extending therefrom upward and backward, a cut- 2gting-blade edged on its entire periphery and pivoted on the shank, andmeans for securing the blade in any desired adjustment, substantially asand for the purpose described.

2. The slotted horizontal plate A, inclined 31 shank B, pivotedtriangular blade E, bolt C, and nut I), all constructed, arranged, andoperating in combination, substantially as and for the purposedescribed.
